I upgraded to Ubuntu 12.04.1 and now libvirt (via open nebula) successfully runs vms but they aren'
t finding the 2 drives (specifically, the boot drive). One is "hd" the other is "cdrom".
The machine boots but fails and displays something like "boot media not found hd" (this was in a vnc terminal and I didn'
t copy the output anywhere so that's not the verbatim message).
I tried constructing a new disk using the new version of qemu (via vmbuilder) and this new machine has the same problem as the old machine.
In case it matters (I can'
t see why it would) I'm using open nebula to manage the machines.
There's nothing relevant in any of the logs: syslog, libvirtd, oned. Which is to say nothing interesting/anomalous is reported when the machine is brought up.
